I agree with Rosie. There are soo many hybrids out there (especially with Phals) that look very very similar, if not identical, that there's no way to tell them apart. The culture advice for all of the hybrid Phals is all the same anyways.
So, just be happy that it's beautiful, and grow it to the best of your ability!
